DATA COMPRESSION AND ABNORMAL SITUATION DETECTION IN A WIRELESS SENSOR NETWORK
First Claim
Patent Images
1. A wireless communication system comprising a destination node and one or more sensors, wherein:
- the sensors gather first data having first dimensions;
second data is generated from the first data, the second data having second dimensions less than the first dimensions;
if the second data is an approximation of the first data within a set of distortion parameters, the second data is transmitted to the destination node;
else the second data is not transmitted to the destination node.

Abstract
Wireless communication systems adapted for compressing data prior to certain communications. Data compression may be limited or skipped when it is determined that the data compression may cause an unacceptable amount of data to be lost. Abnormal situation detection as part of data compression is included. Methods associated with such systems are also encompassed.

9. A method of operation within a wireless communication network, the wireless communication network including at least one destination node and one or more sensors, the method comprising:
-
performing a data transfer function including the following steps;
capturing first data using the sensors, the first data having a number of dimensions;
transforming the first data into second data having a reduced number of dimensions; and
determining whether the second data approximates the first data within a distortion parameter, and;
if so, transmitting the second data with addressing instructions for reaching the destination node. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A wireless communication system comprising a destination node, one or more infrastructure nodes, and a number of sensors, wherein:
-
an infrastructure node receives first data from the sensors, the first data having a first set of dimensions;
the infrastructure node generates second data from the first data, the second data having a second set of dimensions, the second set of dimensions being reduced from the first set of dimensions;
the infrastructure node determines whether the second data provides an approximation of the first data within a set of parameters; and
;
if so, the infrastructure node directs the second data to the destination node. - View Dependent Claims (20, 21)
